Advanced direct coal liquefaction concepts. Final report, Volume 2

PDF Version Also Available for Download.

Description

Integration of innovative steps into new advanced processes have the potential to reduce costs for producing liquid fuels. In this program, objective is to develop a new approach to liquefaction that generates an all distillate product slate at a reduced cost of about US$25/barrel of crude oil equivalent. A Counterflow Reactor was developed in cooperation with GfK mbH, Germany. Advantages are low hydrogen recycle rates and low feed preheating requirements. Coal/heavy oil slurry is injected into the top of the reactor while the recycle gas and make up hydrogen is introduced into the bottom; hydrogenation products are withdrawn from the ... continued below

Description

Integration of innovative steps into new advanced processes have the potential to reduce costs for producing liquid fuels. In this program, objective is to develop a new approach to liquefaction that generates an all distillate product slate at a reduced cost of about US$25/barrel of crude oil equivalent. A Counterflow Reactor was developed in cooperation with GfK mbH, Germany. Advantages are low hydrogen recycle rates and low feed preheating requirements. Coal/heavy oil slurry is injected into the top of the reactor while the recycle gas and make up hydrogen is introduced into the bottom; hydrogenation products are withdrawn from the top. PU study resulted in distillable oil yields up to 74 wt % on feed (dry ash free) from coprocessing feed slurries containing 40 wt % Vesta subbituminous coal and 60 wt % Cold Lake heavy vacuum tower bottoms. Technologies developed separately by CED and ARC were combined. A 1-kg/hr integrated continuous flow bench scale unit was constructed at the ARC site in Devon, Alberta, based on modifications to a unit at Nisku, Alberta (the modified unit was used in the preliminary economic evaluation).
